Vectoring of a wall bounded planar jet using synthetic jet actuator

Jet vectoring is one promising aspect among the various utilities of synthetic jet. In practical applications especially in an internal environment, the development of an air jet is often subjected to wall constraints. This study investigates the vectoring performance of a wall constrained jet with the actuation of a nearby synthetic jet. It is found the deflection of the wall constrained jet is only limited to a small region around the jet exit. The recirculation formed due to the existence of the wall is the main resistance to prevent the primary jet from complete vectoring. By applying a secondary synthetic jet acting as a pushing effect, constant deflection may also be achieved for the wall constrained jet.
